What C/P actually tests
C/P covers general chemistry, physics, organic chemistry, and biochemistry as they apply to living systems. Passages are frequently experiment-based, and many questions ask you to set up and estimate calculations without a calculator.
The section rewards two distinct skills: content fluency (knowing the relationships) and quantitative rhythm (setting up problems quickly and estimating cleanly under time pressure). Students often have one without the other.
Reading a 124 honestly
A 124 in C/P is in the 46th percentile on the official AAMC section table, in the broad middle of the 118 to 132 scale. Section scores here are common, and what they mean depends on the company they keep: a 124 next to three stronger sections reads differently than a 124 in a balanced line.
For a Retaker, a middle section score is often the best value target on the whole score report, because moving it usually requires refining execution rather than relearning a subject from scratch.
How Retakers move this section
C/P improvement on a retake usually starts with separating calculation misses from reasoning misses. A wrong setup means a content fix. A right setup with a wrong final choice usually means a trap or units slip, which is a different kind of practice entirely.
Mental math is trainable and high-yield here. So is drilling official material: the AAMC Chemistry Question Pack for volume and the C/P Section Bank for the reasoning-heavy top end.
Common questions
Is a 124 C/P score good?
A 124 in C/P is in the 46th percentile on the official AAMC section table, meaning 46% of section scores were equal to or lower. Whether it is strong enough depends on your total score, your section balance, and your target programs.
What percentile is a 124 in C/P?
On the AAMC section percentile table in effect May 1, 2026 to April 30, 2027, a 124 in C/P is in the 46th percentile.
How do Retakers improve C/P?
C/P improvement on a retake usually starts with separating calculation misses from reasoning misses. A wrong setup means a content fix. A right setup with a wrong final choice usually means a trap or units slip, which is a different kind of practice entirely.

Section scores only mean something in context. For scale, a 124 across all four sections would land near a 496 total. Compare nearby C/P scores: a 123 in C/P and a 125 in C/P, or see how a 124 reads in the other sections: CARS · B/B · P/S.
